The baby boys, Tristan and Sasha, were delivered "just after the full moon," an event said to induce labor in some moms. Elsa Pataky and her sons are already home and doing great after their delivery last week.

As Hollywood names go, Tristan and Sasha are hardly the most odd we've ever heard. The meaning behind the names makes them absolutely perfect for the sons of Thor.

Tristan, a Welsh name, comes from the word meaning "noise." (Let's also point out that Tristan was the name of Brad Pitt's character in Legends of the Fall, just for fun. And for the memories of long-haired Brad Pitt.)

Sasha means "defender and helped of mankind." Perfect, right? Sounds like this baby has a future in action films just like his daddy.

The brothers join 22-month old big sister India Rose in the Pataky-Hemsworth clan. The family resides in Los Angeles.
